Glooko has tested the market with a soft launch in Europe and said its app is the first on the market to work with all popular glucose measurement devices. The company plans to soon add features that will share blood data with people's doctors.

Users require a special cable to retrieve their data from their blood monitoring devices. A wireless connection is not available.

So what's special about what looks to be a simple app that collects glucose data? Clearly, there's more to this investment than meets the eye.
